NEW HARD/SOFTWARE cComBOoSs

PRODUCE

DYNAMITE COLOR-Byw GRAPHICS

By Norm Lehfeldt

High-resolution black-and-white or color screen duaps for
both the Timex/Sinclair 2048/Spectrua and the Sinclair @L are
implemented with two new software packages.

For the GL, Don Thoapson of Martinez, CA has produced a
monochrome duap utility for the Olivetti PR 2300, ink-jet
printer and a full-color duap for the color ink-jet printer
built by Canon and marketed also with Radio Shack and IBM
nage plates.

The sonochrome utility reproduces the colors from the OL

screen aS a series of different stipples so that there is
pleasing contrast between adjacent areas of different colors.
The color duap reproduces the colors on the QL screen with
remarkable accuracy, given the differences between color
phosophors and color inks.

Both of Don’s progrags reproduce the screen either as a
one-page, full-size horizontal dump or in ’zoom’ aode which
magnifies any selected portion of the screen by two
diameters. Using this feature it is possible to copy the
whole screen on two strips of paper which can then be taped
together for a poster-sized print-out! Both prograas offer
positive or negative image print-outs. In the color prograa
only black and white are swapped in the negative aade. This
feature is especially useful in printing ’Ease’ graphs,
since you don’t waste a lot of ink reproducing the black of
the sonitor screen. Both utilities also feature
well-thought-out SuperBASIC loader prograas which let you
select the various options fros attractively designed aenu
screens.

Don’s programs are marketed by Curry Computer.

For the 2068, Dave Franson has created and is marketing a set

_Of color screen duaps that reproduce that coaputer’s color

displays on the same Canon-Radio Shack-1BM color ink-jet
printer.

The fully-relocatable sachine-code routines (and their BASIC

loading-relocating programs) are provided on opposite sides
of a single cassette and produce either a? i/4" YX 3" or a
4.5" ¥ 6" color screen dump. It should be possible to load
both drivers at once and switch back and forth between isage
sizes by appropriate USR calts. (I believe it is also
possible to load them along with Jack Dohaney’s relocatable
AERCO I/F driver and thus have your program switch easily
between text and graphics printing.)

Supplying the two drivers separately greatly enhances the
flexibility you will have in incorporating them into your own
prograas. Only the AERCO printer interface is supported by
the drivers.

FROM SEPT. 15-28 YTUICE NSL.

Amstrad To Bow New IBM
Compatibles From $595

sonal computer market on its ear, Am-
strad, the maverick British consumer
electronics marketer, has announced plans
for the introduction and international sale
of an eight-model line of low priced IBM-
compaubles.
The new models range from a leader

frat to set the $34 billion world per-

designed to list in England at about $595.

to a high-end business oriented version
with color monitor and hard disc drive at
under $1,500. Alan Sugar, Amstrad's
chairman, says the machines are already
being turned out in the Far East on a pro-
duction schedule that calls for a rate of
70,000 monthly, and that he is looking for
sales in Europe of 300,000 total units by
the end of this year.

A sales start in the US. is scheduled for
early next year, and Sugar says he should
be able to move 50,000 to 60,000 a
month here. Production in 1987, he
claims, will then jump to 100,000 month-
ly, and worldwide sales for the year
should hit at least 800,000. If Amstrad

even comes close to its volume goals, it
could put a severe competitive crimp in
the marketing plans of the U.S. low end
computer leaders Atari and Commodore,
while siphoning off a major chunk of busi-
ness from a host of smaller computer com-
panies marketing low-end IBM clones.
Relatively unknown here, Amstrad has
through sharp pricing and marketing tac-
tics established itself as a major video and
audio equipment company in the U.K.,
and one of the biggest players in the Eu-
rope-wide computer market, with a 34
percent share. Last spring it acquired Sin-
clair’s computer business, along with con-
sumer electronics brand rights, for $7.5
million. Just now finding its way into
stores here is Amstrad’s Korean-made
packaged $799 personal word processing
system that includes a computer, disc
drive, software, monitor and printer. It's
being distributed under an exclusive
agreement by Sears World Trade Corp.
Whether Sears will also handle Amstrad’s
new IBM compatible PCs is uncertain.

BETTER RGB CIRCUIT
by Joe Williamson

FROM THE JULY 1996 SUH NY/L.

LETTERS Electronics / August 7, 1986

Sinclair is still kicking
To the editor: Your issue of June 23 con-
tains a serious error. It is not true that
Amstrad Consumer Electronics ple
bought Sinclair Research Ltd. [Elec-
tronics, June 23, 1986 p. 53]. They sim-
ply bought the existing computer range
and the right to the use of the brand
name. They have no right to any future
computer products or any other product
categories. A portable computer is un-
der development, but by my team and
for my company. We plan to launch it in

the first half of 1987.

Str Clive Sinclair
Chairman
Sinclair Research Ltd.
London

The circuit described in the february
1986 issue of SUM was designed around the

Sears RGB/TV/Monitor (same as the Sanyo
model # 31C426) and the Magnavox (NAP) r r‘
RGB-40 or 80. Pn ae Composite
of QY | 100 PF Syne
Both of these monitors (and the QL in 2068 Out
monitor as well) take negative-going eek

composite sync and active high RGB signals
and have well buffered inputs to clean up
any poor inputs.

Many RGB monitors out on the market
don't have these features and therefore do
not work very well or at all with the

circuit described. With the simple
addition of a 74LS86 Quad 2-input
Exclusive OR gate, you can shape (buffer)

and invert all four signals to what ever
format you need by changing the polarity
of one of the two input lines on each of
the four gates.

Also, I neglected to say what
transistor was used in the original
circuit; it is a 2N2222, Radio Shack #276-
2009. Although, any garden variety NPN
transistor should work.

deals with the trans-

MTrERM Srure
By Bill Strick

Now that there is a sizeable oroup of RODEN Owners. perhaos

a little advice concerning the use of these sarvels will pro-
mote a sharpening of interest in their use and an increase in
the exchange of useful information between al! of us. Follow-
ing are some hints regarding data transmission via MODEN,

A. TO TRANSMIT (XMIT)
SENDER aoes to BUFFER MEMU and erases Butter contents. Back
to HAIN MENU, EXITS to BASIC and LOADS or MERGES data to be

transmitted. (See Section C for details.)

Phone the person to receive the above data and determine (via
voice) that the parameter settings agree as shows below:

SENDER RECEIVER BOTH
BUF: CLOSED BUF: CLOSED (Opened by MIT: OFF
DUP: HALF DUP: FULL = XNIT OP) = -voRD: 7
LF: ON LF: OFF STOP: 3
CR: OFF CR: OFF PRTY: EVEN

CON: NONE (text)
‘(HEX for other)

CON: NONE (text) DSP¥: 32
> (HEX for other}

SENDER informs RECEIVER to {!) clear bufter. {2) qo to terminal
mode. and (3) connect uo via MODEM COMNAND ¥,

To access MODEN COMMANDS. press CAPS SHIFT & ENTER together.
ENTER M to connect. SENDER also CONNECTS as described. Both
users leave phone receiver off hook. CONNECT will take place
with a displayed signal and sound,

From this ooint. ANY activity is in the hands of SENDER ONLY!

After CONNECT signal, SENDER opens the RECEIVER’s butter by
executing a CONTROL R {CAPS SHIFT & 7 and then eaters an R).

SENDER sow returns to NAIN/MENU using CAPS SHIFT 8 and calls
up BUFFER MENU. ENTERS T to transmit text in buffer.

ENTER four tines: #1 after prompt- *Prosot Strisq’
#2 after proaot- "Character delay’
#3 returns SENDER to HAIN NENU
#4 enters TERMINAL MODE

This begins transmisson which can be viewed on screen.

After end of transmission. SENDER closes RECEIVER’s butter
with a CONTROL T (CAPS SHIFT & 7. then 1).

SENDER then enters BELL signal (CONTROL G...CAPS SHIFT & 7,
then 6). which signals the end of transmission {XMIT) to
RECEIVER.

Atter BELL, both USERS disconnect by doing a MODEM COMMAND H
(CAPS SHIFT & ENTER . then H) to “Hang up” modems. They can
how converse freely on their telenhones.

NOTE: If “Waiting Caller" service is on SENDER’s phone, it
will be necessary (before using MODEM) to cancel this service
temporarily. This can be done by dialling STAR ("8") 70 for a
touchtone shone or 1170 for a oulsetone phone.

B. TO MOVE NTERN BUFFER CONTENTS TO MSCRIPT

To save eaterial from Moder buffer. first note the length of
Butter used (BUFUSD). Then EXIT to BASIC and SAVE.

To Tape: SAVE "(name)" CODE 26710. (length)
To AERCO BDS: MOVE (drivel: (name) .bin’. 26710, (length)
To ZEBRA DBS: SAVE #"(name)” CODE 26710. (length)

LOAD MSCRIPT. LOAD saved materia] from Home Henu.

C. TO TRANSMIT MSCRIPT FILES OR BIN.COD VIA NTERN
First. move file to MTERM buffer as outlined below:

¥ Make a note of document (file) Jenath {trom a DIRECTORY
or CATALOG listing or from a Header Reading).

% SAVE document to tape or disk.

% LOAD NTERH. Go to Buffer Menu.

% Clear buffer. EXIT to BASIC.

% Open up program area with DIN AS (document length).

Since this expands VARS (not the orogras area):
POKE 23627, PEEK 23641: POKE 23628, PEEK 23442
Now LOAD = from Tane: LOA "* CODE 26710
from AERCO BPS: CAT "(érive): (name). bin’. 26710
from ZEBRA DBS: LOAD & "(nase)" CODE 26710

The command. PRINT USR 54016. will restore MTERM with document
fully installed in its Buffer and ready for transmission.

NOTE: Some BBS systems require LF after each line. so you may
have to add them before leaving NSCRIPT.

IMELINE Greetings Fellow Sinclair Users, | 260 |

We are two people who still get a great deal of
Satisfaction out of our humble computers. We've spent many, |
many hours telecommunicating all over the U.S. to every w
BBS that we could find which supports our machines. We did 7
not want all this effort and time to be wasted on our own
uses alone. So we got together and wrote a small publication
called,"The T/S Guide to telecommunication".

This is an entirely FREE publication, no copyrights
will apply. We enclose an outline of the document in pro-
gress. We intend to send you a copy when it is ready. In
the mean time, we wanted you to have the information on
the enclosed chart which gives the names, numbers,hours and
settings of all the boards that we could find. We would
hope that you could see fit to publish this in your User
Group Newsletter. Failing that we would hope you might
make it available to all your members by xeroxing at the
User Group meeting. As I said, we spent many,hours on the
phone verifying all this information, and are prepared to
say that it's accurate (until it changes). The guide has a
much more detailed description of each of these boards, as
well as descriptions of all the modems, terminal programs
and hardware add-ons that we could find. It should certainly
be in your hands by the end of October.

Take it easy, and keep on TIMEXing!

This program will display a pie
chart and the values for each of up
to 18 pieces of the pie. If sore
than 18 pieces of the pie are
entered then the %‘s coluan will not
line up with the values entered due
to scrolling. The PLOTing routine
is placed at the beginning of the
program for speed. Depending on the
pie slice densities, typical PLOTing
time can run between 2 and 15
minutes.

REPORT ON MEETING QF NOVEMBER 28th.

Meeting was called to order shortly after
8:@0PM by Joeseph Randall. The meeting was
started by everybody identifing themselves
and there current interests and/or
projects. Reqular members in attendence
were Ivor Alma, Russell English, John
Ezike, Tom Fattaruso, Fred James, Alvin
Lam, Woody McPheeters, Bill Miller, Joseph
Randall, Wayne Seibel, Fred Templeton,
Darwin Thompson, and Kevin Zimmerman. In
addition Erwin Mead from GUTS visisted us,
and we welcomed two new members MATT MOORE
and DANIEL L. MOORE (not related)

Darwin Thompson informed us that the GL has
been selling for as low as 199.808 at At
Computer Response 69-B Island St. Keene, NH
O3431 (46803) 357-1808. He reported that
they can help with almost any added option
to configure a system to anyones needs. It
is unknow if Sunset Electronics is matching
the price. It seems the price decline is
due to an upcomming change in the QL‘s
distribution network.

Russell English brought to our attention
that most parts for the 2048 are available
at most electronics stores except the SCLD
chip which is custom to the 2048. There is
a souce and he reported that the group
could join the other user groups ts
purchase some. A vote was taken to
purchase one for our general inventory,
which did not pass. t was suggested that
those who are interested put up the cash
and share the risk. Price 1-$25.08 3 or
more $18.88.

One of the main events of the night's
meeting was a video of the TIMEX/SINCLAIR
Computer Fest in Cincinatti, Ohio this May
; The video was as exciting as watching
the opening of Al Capone's undergound
vault--empty. The entire 15 minute feature
was a constant Par ny view of the people
there without a stad e feature or
interview. At least we did get to see some
of the exhibitors displays. Although the
video was limited it did show that there
were plenty of people there.

I got a chance to show off my 2848
word-processor with multi-tasking abilities
but I blew it when I POKED the wrong
address into the vector table and caused
the printer output to get scrambled and
ultimately to crash the whole system.
Fortunately I printed out the beginning of
this article on the 2048 printer (while the
EPSON printer was printing something else)
before the crash.

ThiS routine will never cause a Printer to tock up. The time
taken by the 20658 to process a keyboard interrupt is often more
than 158 microseconds. If this interrupt was permitted whi le
STB Was iow, the ACK $ignal could arrive from the Pranter before
STB went high again,

In this routine, interrupts are blocked white the STB pulse 15
being sent.

For those not familiar with STB and ACK, the STB is a Signal
tO the printer that valid data is present on the data wires.
The RACK 35 an acknowledgement signal from the Printer that the
data has been received, and cirer things are normal,

Both $ignals are puises heving the timing stowh ain Figure 1.

The ACK pulse Can be as Short as & microseconds. 2068 code
(OOP LO test if it is there tates longer than thet. Part of the
time the Signal will be missed. That is why the BUSY signal is
tested instead. The reason for the ACK signat is to generate an
interrupt when that operating mode is in USe. The ZEB PIO can
be configured that wey but the 2068 does not operate ins IH2 as a
generat cule, (Vectoréed interrupt mode)

When things are not normal, tike funning out of paper, or the
Printer cover is open; the program heees locrina. In order to
bf@ak out of this Loop, use is made of the ROM Subroutine BREAK?
at sddréss 8281. Usually, this is SUFfACiEnt because printers
indicate when they are at FRULT with an alarm andsor light. If
not, you Might wart 10 test the printer status after calling the
BREAK? routine. This is tine Gilding # lily, though,

BREAK? 38 a short routine Which Senses if both the CAPS SHIFT
and BREAK keys are pressed. It does mOt weit for the keyboard

A printer meeds two routines to bring it on tine. The first * F
aS tO configure the Z6@ PIO interface so it wilt property tate
to the printer, The second is the equivalent of OPEN N3,"C".

There are Six ilems GF information you must provide. You Cah
afrenge fer these (G6 be defautt vatues if you want, For this
article they are variables C1 through C6. The parameters they
represent are:

C1 = TO PRINTER PORT AOORESS

C2 = ABOVE COMHAND REGISTER ADDRESS
C3 = STATUS/STB PORT ADDRESS

C4 = RBOVE COMMANC REGISTER ADDRESS
C5 = BUSy BIT VALUE

C6 s STS BIT VALUE

The following statements accomplish the initialization.

The CLOSE B83 returns control to the 2040 printer.

The OPEN 83,°C" enables LPRINT to the printer, but if you want
COPY and LLIST to work, a Lot more machine Code is needed. This
i$ beCause both Use Lokens and control codes the printer cannot
understand.

If your printer if one Of those with a wired RESET, you must
reconfigure the PIO to address that bit, then restore the work-
ihQ configuration after the reset as completed.
